NTTn STATES PATENT Frio WINTER-ROAD MACHINE FOR CLEARING SNOW.

SPECIFICATION forming part of Letters Patent No. 621,935, dated March 28, 1899.

Application filed April 30,1898. Serial No. 6791397. (N model.)

To ZZZ whom, it may concern:

Be it known that I, SAMUEL FREEMAN Mo- OUSKER, clergyman, of the village of St. Louis de Gonzague, in the county of Beauharnois, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Winter-Road Machines for Clearing Snow, of which the following is a specification.`

My invention relates -to improvements in winter-road .machines for clearing snow; and the object of the invention is to design a machine by which a beaten road over the snow may be produced and kept clear of a superfluous amount of snow, so that it may be utilized throughout the winter; and it consists, essentially, of a road-machine havinga spreadable front plow, a sled for supporting the same, and a draft-tongue for pulling the plow and sleigh, a box-seat andrunners connected thereto, and a rear land-roller, all arranged and designed to be utilized in the manner hereinafter more particularly explained. Figure l is a perspective view of my Inachine complete, a portion of one of the wings of the plow being broken away to exhibit the construction of the front portion of the machine. Fig. 2 is a plan view showing in dotted linestwo of the positions into which the wings of the plow may be adjusted. Fig. 3 is a cross-section through the sled on aline with the adjustable front spindles.

In the drawings like letters of reference indicate corresponding parts in each gure.

A is an ordinary pair of `solid sleigh-runners suitably joined and carrying pivoted near its center the front end of the box-seat B, the rear end of which is supported by a plurality of parallel runners O, arranged laterally approximately at equal distances apart. The runners O are firmly held in their respectivel positions by the cross-beam c, to which they are vertically pivotally attached by the rod o', passing loosely through said runners and iixedly through the spacing-blocks c2, attached to the under side of the cross-beam c. Rising vertically from the upper side of the cross-beam c, near its ends, are the fixed posts c3, which pass through holes b' in the outer ends of the cross-beam t, attached to the rear end of the box-seat B. Encircling the posts c3 and supporting the cross-beam b are the helical compression-springs c4, thus allowing the runners O to adapt themselves to irregularities in the road-bed over which they may be drawn. This my preferred adjustment may be dispensed with and the same result accomplished by having the seat-box B rigidly attached to the cross-beam c and its front end loosely pivoted to the sleigh A by an ordinary ball-and-socket joint. Thus the seat-box would have a perfect angular play on the sleigh A.

Loosely pivoted to the rear end of the seatboX B by a tongue CZ is provided the ordinary land-roller D, which I preferably weight by having its axle CZ' made of a heavy piece of timber, which is attached to the cylinder of the roller by the closed ends d2 and journals in the rectangular frame d3, to the front of which is iirmly ixed the tongue CZ and on the rear of which is placed the platform d4, adapted to carry a number of men when extra weight is required to more compactly roll the snow.

The scraper d5, pivoted beneath the platnr form d4, is normally held away from the roller by helical compression-springs db', above the platform where they protrude, and the crossbar (Z7, joining their ends, but may be pressed down into contact with said roller by footpressure upon said bar Z7 for the purpose of clearing the roller from snow.

Rising vertically, well to each side of the center, from the cross-bar a', attached to the sleigh or in front of thepivot a, are fixed posts 0.2, adapted to guide the vertically-adjustable cross-bar E, through the ends of which screw the hand-screws e, the lower ends of which are j ournaled in the ends of the fixed cross-bar a and are preventedfrom vertical play by the collars e' and e2.

Passing through a rectangular hole e3 at the center of the cross-bar E is the tongue F, which has a horizontally-pliable joint f, so arranged as to normally come within the hole e3, where it is held by the bolt f', passing through the tongue, and horizontal lugs formed on the rear side of the cross-bar E above and below the hole e3. On each side of the tongue centrally of its length are arranged the toothed racks f2 on the forward part and f3 on the rearward part of said tongue in such a manner that when the bolt f is withvdrawn and the tongue is shoved inwardly IOO they engage with and revolve the gear-pinions E, which are journaled horizontally on each side between the standards E2, attached to the cross-bar E. Parallel guide-strips e4, opening out in front, are attached to the sides of the hole e above and below and at each side of the tongue F, against which they act above and below the racks f2.

Across the front of the sleigh A is supported by the vertically-adjustable clevises d3 the cross-bar G, upon which rests the forward end of the tongue F and upon which it has end play and also sideplay as far as the stops g, fixed to the said cross-bar G.

On the ends of the cross-bar G are fixed the guide-rings g', through which pass freely the rods II, the rear ends of which incline inwardly and pass through the holes e5 in the cross-bar E and have on their inner side the racks 7L, which mesh with the pinions E'.

Attached to the underside of the tongue F is the plowshare I, which sweeps forward at its lower end and broadens out, forming pivots z' for the lower front corner of the wings or moldboards J, which are curved forwardly at the lower edge in conformity with the shape of the share I. The upper forward edges of the wings J have extensionsj, the ends of which are pivoted to the tongue vertically above the lower posts t'. Attached to the l'ear sides of the wings J at their ends are the horizontal rods J which pass loosely through the rings h', formed on the outer ends of the rods II. Suitable whifiietrees and neck-yoke are arranged on the tongue F for the attachment of draft-horses.

Having now described the Various part-s of my invention, I shall nowpoint out their uses and method of operation.

XVhen a road is desired to be formed through newly-fallen snow, horses are attached to the tongue of my winter-road machine in the usual manner, the snow-plow having been adjusted to the required levelY to throw aside the desired amount of snow by the clevises in front and the hand-screws e at the rear, and the machine started, forming a good track in and rolling down the snow not cast aside. During early winter I preferably keep the plow well raised, so as to track and roll down most of the snow and not form high snow walls at the side. During the later winter, when a good depth of snow has been packed on the road, I lower the plow and throw the surplus snow aside, as then snow walls can be formed without danger to traffic, nor will they be so high as if added to each snowfall from the beginning of the winter. It will be noticed that as my snow-plow is pivoted to the tongue it moves sidewise With it, facilitating turning. (See dotted lines, Fig. 2.) Vhen' a drift is required to be cut away, the bolt f is drawn and the horses backed, shoving the tongue inwardly and causing the outer ends of the wings to move outwardly by the action of thc racks f3 on the pinions B and their action on the racks II. Thus the wings are placed in the forni roller D by placing on the platform a number of men who are generally available for the purpose in rural districts for which my invention is particularly adaptable.
